If you are having problems with a digital thermostat, there are a few simple tests that can be performed to isolate the problem and help you decide whether to replace the thermostat to fix it. Step 1 – Check Temperatures Before getting too involved in testing, check the room temperature on a digital thermometer. If the temperature matches what is being shown on the thermostat, you can verify that the room temp sensor for the thermostat is working. Any discrepancy here indicates a bad thermostat sensor. While the sensor can probably be replaced, it is more cost and time effective to simply replace the entire unit. The next step will be to check the set point calibration. Step 2 – Calibrate the Room Temp Digital thermostats can be calibrated, meaning that both the set point and room sensors are brought into balance. Since each thermostat is made differently, you will have to refer to the thermostat instruction manual in order to calibrate the unit correctly. If the manual is not available, call the manufacturer and ask to speak to a service technician; that person should be able to walk you through the simple process.

STEP 3 Disconnect all the thermostat wires from the thermostat and label them according to which terminal they connected to.

Remove the wall plate from the wall. Mount the wireless thermostat receiver wall plate to the wall with drywall anchors and screws.

STEP 6 Mount the receiver to the wall plate by pushing it on until it snaps into place, or tighten screws as required.

How to Install an Electric Baseboard Heater Thermostat

I really appreciate your info and it gives me a lot of ideas. One problem with any manual thermostat solution that’s not automatic is this: I could trivially put another switch breaking the thermostat line on the wall near the door, but it’s not exactly what I need. The scenario that I’m trying to avoid is that my wife has a garage control on her key-chain and has accidentally hit it a couple of times in her pocket or purse.

That probably means you’re wanting to know how you can hook up multiple heaters to one thermostat. Here’s what you need to know: Rule #1: The number of heaters that you can safely wire to one thermostat will depend on the size of your breaker in the electrical box.

I would like to put in a new programmable thermostat but I don’t have enough wires. This is a common problem when replacing a mechanical thermostat or a thermostat powered by batteries. These older thermostats require 4 wires, but newer more sophisticated thermostats require a 5th wire known as the Common wire to power the digital display. There are two ways to add the common wire to a four wire installation: Before starting, we recommend that you take a picture of the original wiring to the old thermostat as reference to help remember what terminal each thermostat wire was connected to.

The easiest and least expensive option is to sacrifice independent control of your indoor fan. At your heating and cooling equipment repeat the same step and move the G terminal wire to the C terminal. At your heating and cooling equipment place a jumper wire from the Y equipment terminal to the G equipment terminal.

The thermostat I bought has the capability to automatically change over from heat to cool and vice versa to maintain the temperature setpoint. This is very desirable for dealing with those nights where it gets very cool but then warms up in the AM before you arise.

Super Thermostat I have two heat pumps to heat and cool my house. The house layout is such that there is no path from one part of the house to another for a big old air duct and two of them offer redundancy in case of failure. I have really nice programmable thermostats on the systems that can shut them off during the peak period but there are still a few things that would be nice to have.

Ability for each of them to know when the other one is on to prevent both of them from coming on at the same time, or restrict each thermostat to a specific period of time so they don’t overlap each other. Be able to adjust both of them from the same spot so you don’t have to run back and forth. Be able to tell if either of them are on and what they are doing when wondering what is eating up the power. Keep visitors from playing with the temperature when they think they’re getting too hot or cold.

Sounds like a job for a couple of Web enabled thermostats doesn’t it? Enter another Arduino, this time a thermostat.

Hook up thermostat for Outdoor Wood Boiler

This thermostat is designed for a system with five wires — the wire terminations are marked as follows: W – This wire comes from the relay that turns on the heating system. Y – This wire comes from the relay that turns on the cooling system. G – This wire comes from the relay that turns on the fan.

Someone with more control knowledge might help you if you want it all on one thermostat and it will have to be the correct model for doing that. The boiler is set at 74 and the gas is set at 70 or something. If the wiring and control is totaly escaping you you might want to invest in a furnace man for a few hours but you need to be able to tell him exactly what you want done which is simply switch the fan on high speed and off with a thermostat for the boiler heat and the gas furance and control gets left alone.

Now I dont want to add to your confusion at this point but the one and only potential problem with this type of control is that if you let the fire go out on the boiler the fan is going to run continuously as the thermostat is going to be calling for heat that cant be delivered, Got it? The gas furnace will still cycle its burner to maintain the heat setting of that thermostat but the boiler ‘stat is going to keep the fan running all the time.

This would be the only reason I can think of to have the second aqua-stat mounted somewhere to sence heat in the exchanger. No heat in the water, the fan cant run. For all the added complication I just plan to keep the fire going.
